IMPROVEMENT IN JOINTS FOR CARRIAGE-TOPS.

Specification forming part T0 or whom it may concern:

Be it known that we, A. C. SHELTON and BYRON TUTTLE, of Plymouth, in thecounty of Litchfield and State of Connecticut, have in vented a new anduseful Improvement in Joints for Calash Carriage Tops and the Mode ofSecuring the Bows Thereto; and we do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the annexed drawings, making a part of this specification, in which-Figure 1 is a side view of our improvement. Fig. 2 is a perspective viewof the same. Fig. 3 is a vertical section of the same, the plane ofsection bisecting the joint longitudinally with its pintle or bolt.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in providing the lower end of the calash-armswith circular plates and shoulders, in the manner and for the purposeshereinafter set forth.

To enable those skilled in the art to fully understand and construct ourinvention, we will proceed to describe it.

A B C D represent four arms constructed of metal, cast or wrought. Thelower ends of the two arms A B are bent so as to form right angles withthe outer portion and a circular plate is formed at the end of the bentportion of each arm. (See Figs. 2 and 3, in which a, represents theplate of arm A and b the plate of arm B.) The inner ends of the two armsC D are nearly in line with the outer ends. These arms have circularplates formed 011 their inner ends. These plates are both shown in Figs.2 and 3, 0 representing the plate of arm C, and d representing the plateof arm D. The plates of the several arms are of equal diameter. They areplaced side by side and a pintle or bolt E passes through their center.The inner end of each arm has a shoulder e formed on it, and theseshoulders extend the whole width of the several plates, as shown clearlyin Figs. 2 and 3.

One end ofthe pintle has a head f formed of Letters Patent No. 18,992,dated-December 29,1857.

on it, and the opposite end is provided with a screw-thread, on which anut g is fitted.

The plates of the arms are allowed to turn freely on the pintle E, and awasher p is placed on the pintle, said washer being interposed betweenthe plate a and nut g, as shown in Fig. 3.

The outer ends of the arms A B C D have sockets h formed on them. One ofthese sockets, the one 011 arm B, is shown clearly in Fig. 1. Thesockets are of slightly taper form and are made sufficiently long toreceive and firmly hold the ends of the bow t. The lower ends of thesockets at their junction with the arms have beads j formed on them, oneon each.

The bows 71 are covered with patent leather, cloth, or other material,and in consequence of having the bows fitted in the sockets h, as shown,the covering may be neatly adjusted on the bows and made to extend downas far as the beads j at the lower ends of the sockets, making a veryneat and finished appearance.

It will be observed that the plates a l) c (1 form, when combinedtogether, a barrel, and that the shoulder e of each arm rests upon andextends across the entire length of said barrel. The shoulders e arethus made to form a wide base for the arms, so that any' injury from alateral movement of the arms,

is impossible.

'Having thus described our invention, what we claim as new, and desireto secure by Letters Patent, is

Providing the lower end of the arms A B C D wit-h circular plates at b cd and shoulders c, said plates being so arranged as to constitute abarrel, over which the shoulders 8 may move, said shoulders givingsupport to the arms A B C D, all substantially as described.
